I'm interested in the live gamer 4k PCI-E card so I can play in 4K HDR but stream in 1080p. I just wanted to know will the card fit on my motherboard? I have attached two images where the card can possibly slot into. Please advise whether it will fit if I remove the card between my 2 graphics cards. Or if it can fit in the first image slot? I have highlighted the areas in the images.

Assuming that your motherboard is a Maximus VIII Hero then the only x4 slot is the bottom most long one, all of the short slots are x1.

You mean where the red sound card is? Could I possibly move that sound card to the slot between the graphics cards highlighted in red and put the capture card in the bottom slot? Or wont the sound card work in the pci-e slot between the graphics cards?

Also is there a pci-e extender of some sort possibly to maybe increase slots?

So I just tried moving the sound card to the slot in between the gpus. And the second gpu managed to get caught on the pin to pull the card out of the pcie slot and I managed to get the card out and now it says both of my gpus are not working. Pulled one gpu out and the first gpu is not even working nor will install nvidia driver update.
